MOP-.WRINGER.

SPECIFICATION forming part of Letters Patent No. 762,252, dated June '7,1904,

Application filed May 13, 1903,

To all whom it may concern:

Be it known that I, EDWIN PRESCOTT, a citizen of the United States,residing at Arlington, in the county of MiddleseX and State ofMassachusetts, have invented an Improvement in Mop-Wringers, of whichthe following description, in connection with the accompanying drawings,is aspecification, like letters on the drawings representing like parts.

My invention consists in a new and improved mop-wringer of thetypeemploying a pail provided with a pair of wringing-rollers having arelative movement toward each other and suitable mechanism for effectingnecessary relative movement of the rollers.

My invention will be best understood from I the following description,taken in connection With the accompanying illustration of one specificembodimentthereof, while its scope will be more particularly pointed outin the appended claims.

Referring to the drawings, Figure 1 is a plan view of the describedembodiment of my invention. Fig. 2 is a side elevation of the same,showing the rollers in their normal or separated position and thetreadle in its elevated position. Fig.- 3 is a similar elevation showingthe rollers in proximity and the treadle in its depressed position; andFig. 4 is a sectional elevation on the lined 4, Fig. 1..

In the drawings, a is a water-holding receptacle, herein termed a pail,of any'suitable form, material, and size. I have herein shown the sameas having a substantially rectangular cross-section with substantiallyvertical side walls, but with an inclined or undercut end wall, althoughthis form and construction may be widely departed from. The pail isprovided with a suitable bail or handle 6, pivotally secured to theoverturned pail-rim, and is also provided with the substantiallyhorizontal base-bail c, secured'near the bottom of the pail andprojecting outwardly from the undercut front end thereof to give anextended base-support therefor and presenting supporting-surfaces, asthe bail edge 0 and the underturned foot 0 beneath the level of thepail-bottom, to elevate the same from the floor or other support when inuse. This maintains the pail-bottom clean and dry, and

since it relieves the bottom surface of all wear the corrosionordinarily experienced with mop-wringers of this type, where the wornsurface contacts with the alkaline solutions often employed, isprevented. A roller cl, which may be of wood or other suitable materialand herein shown as stationary, is journaled in the overturned rim ofthe side walls near the pail-front, and the cooperating relativelymovable roller e is journalcd in the yoke-shaped fulcrumedroller-carrier f, having its two bent or offset legs fulcrumed at g,about which it is adapted to swing to'bring thesaid roller 0 against theroller (Z, as shown in Fig. 3.

The base-bail 0 is curved upwardly at the sides of the pail to provide afirm support for the carrier-pivot at its fulcrum 9. Each leg 7 of theroller-carrier is connected at the opposite side of its fulcrum gthrough connectinglink IL with the end of the bent or angular leg of thefulcrumed yoke-shaped treadle-carrying member 2', which is normally heldin a substantially horizontal position, as shown in Fig. 2, by thespring j, secured to the link it and one leg of the yoke to force thesame apart and maintain the rollers in their separated positions. Theyoke z' is fulcrumed upon the rod 70, extending through the overturnedrim of the pail-top from one side to the other and above the usualwater-level therein, and is provided with a treadle, as Z, by which itmay be readily depressed from the position in Fig. 2 to that shown inFig. 3

to throw the levers f forward and the rollers together.

Referring particularly have provided cooperating gathering members m,secured to the side pail-walls, extending forward with a slight downwardinclination and presenting gathering-Walls diverging in both directionsfrom the line of bite between the rollers. The rear ends of thegathering members are also in the appropriate location to provideadditional bearings for the fulcrum-rod in to stiffen thereby the entirepail structure. The forward divergence of the gathering members is atsuch an angle that the lateral thrust against the same when the mop issqueezed between the rollers is to Figs. 1 and 4, I

taken up substantially lengthwise the said members or in a directionpresenting the greatest resistance, and the structure is there.

by materially stiffened.

When the mop-wringer as above described is used, the pail is filled withwater ordinarily to a level at or beneath that indicated in dotted linesin Figs. 2 and 3, and as the mop is about to be withdrawn from the waterwithin the pail the treadle is depressed from the position shown in Fig.2 to that indicated in Fig. 3 to force the roller 6 forward to pinch orsqueeze the mop between the same and roller d as the same is withdrawnfrom the pail, the gathering members cooperating to gather the ends ofthe mop and deflect them toward the center.

In wringers of this type as heretofore constructed the depressedposition of the treadle has been such as to apply the downward pressurethereon in a vertical line comparatively remote from the vertical lineof the rollers, the upward pull upon the mop and the downward pressureupon the treadle producing a turning moment tending to upset the pail.It will be observed that in the embodiment of my invention herein shownthe treadle Z, which has an initial position immediately in front of theroller d, is so fulcrumed as to have a movement downward .and inwardunder the undercut front pail-wall, having a final depressed positionsubstantially beneath the rollers, thus bringing the downward pressureupon the treadle and the upward opposite pull upon the mop insubstantially the same vertical line and preventing all tendency for thepail to overturn from this cause. By the inward and downward movement ofthe treadle the application of pressure thereto when in the depressedposition is in a vertical line near the vertical line of the center ofgravity of the pail, and the unstability of the pail is thereby reducedto a minimum, and its base-bail 0 may be correspondingly shortened. Theextension of the fulcrum-rod is from one side wall of the pail to theother provides a firm fulcrumed support for the treadle adapted toresist the downward treadle-pressure. It will be further observed thatby the bent form which is given to the legs of the fulcrumed carrier fsuch carrier, with its connecting-yoke above the roller 0, is so locatedto the rearward relatively to the roller as to avoid all interferencewith the mop-head when the treadle is depressed and the rollers arethrown forward. This condition will be noted by observing the positionof the connectingyoke in Fig. 3, where it is almost vertically above theroller 0 instead of having in that position of the roller a locationconsiderably to the front of its position there shown, which would bethe case were the legs f straight and not inclined. By comparing thepositions of the levers in Figs. 2 and 3 it will also be seen that therelative arrangement of the two fulcrums and the inclination of the twolegs of the roller-carrierf and the treadle-carrier '5 gives arelatively increasing leverage for both roller-carrier f andtreadle-carrier 41 during the operation of the treadle, and consequentlyan increasing leverage and decreasing roller movement of the entirelever system during operation.

It will be obvious that the specific embodiment which I have hereinshown is for illustrative purposes only and that suitable modificationof the details thereof, of the lever connections, the location of therespective fulcra, and the construction and relation between therespective parts may be made within wide limits without departing fromthe spirit of my invention.

I claim 1. A wringer comprising a pail having a flaring front end wall,a plurality of rollers one of which is positioned over said flaring walland a roller-moving treadle for the other roller, said treadle beingfulcrumed adjacent the top and rear corner of the pail whereby itsdepressing movement carries its foot-receiving portion from positionbeyond said flaring wall into a position under said wall and the rollerpositioned over the same.

2. A wringer comprising a pail having a flaring end wall, a plurality ofrollers one of which'is fixedly positioned over said flaring wall andclose-to the edge'of said pail, carrierarms for the other roller, saidcarrier-arms being fulcrumed near the bottom of said pail, aroller-moving treadle fulerumed near the top of said pail and at theside thereof which is opposite said flaring end wall whereby depressionthereof carries its foot-receiving portion from position beyond saidflaring wall into a position under said wall, and under saidfixedly-positioned roller, said roller-carrying arms and said treadlehaving their ends respectivelyextended beyond their respective fulcraand connecting means operatively connecting said extended ends for themovingof said arms by said treadle, said carrying-arms between theirfulcra and the pointsat which said roller is mounted therein beingdeflected from a straight line and having their ends connected by aconnecting member arranged externally to said roller said connectingmember being removed by the deviation in said arms, from the line ofdraft of the mop from between said rollers.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDWVIN PRESCOTT.
